Neural network generative models have achieved impressive results in recent years, but researchers are still working on increasing their efficiency. Researchers from the HSE Faculty of Computer Science and AIRI have managed to optimize the finetuning of the StyleGAN2 neural network, which creates realistic images, to new domains, reducing the number of trained parameters by four orders of magnitude. At the same time, the quality of the obtained images remained high. The results of this work were presented at the NeurIPS 2022 conference.

Using a multidimensional approach, sociologists from HSE University have identified some vulnerable categories of the population that have rarely been the focus of research on poverty. According to their calculations, pensioners and people with disabilities also fall into the ‘poor’ category. The study was published in the Russian Journal of Economics.

Researchers at the HSE Faculty of Economic Sciences Laboratory for Wealth Measurement analysed income and cost of living data at the sub-regional level in Russia (municipalities) and in the US (counties). The study reveals that territorial differences in the cost of living are more pronounced in Russia compared to the United States. However, the distribution of overall income across settlements of varying sizes is quite comparable in both countries. The article has been published in the HSE Economic Journal.

An international team including HSE researchers has conducted the largest ever cross-cultural study of appearance-enhancing behaviours. They have found that people worldwide spend an average of four hours a day on enhancing their beauty. Caring for one's appearance does not depend on gender, and older people worry as much about looking their best as the young do. The strongest predictor of attractiveness-enhancing behaviours appears to be social media usage. The study findings have been published in Evolution and Human Behaviour.

Between March 27 and May 17, applications are open for the Mirror Lab Project Competition. As part of the new applications campaign, the HSE University bulletin (Okna Rosta) is publishing a series of interviews with the winners of last year's competition. In this issue, Natalia Kryzhanovskaya and Maxim Solodovnik speak about nano- and quantum technologies, as well as cooperation between HSE and Southern Federal University (SFedU).

HSE researchers, in collaboration with their colleagues from Skoltech and the Central Research Institute for Epidemiology, have uncovered the mechanisms behind the emergence of new and dangerous coronavirus variants, such as Alpha, Delta, Omicron, and others. They have discovered that the likelihood of a substitution occurring at a specific site of the SARS-CoV-2 genome is dependent on concordant substitutions occurring at other sites. This explains why new and more contagious variants of the virus can emerge unexpectedly and differ significantly from those that were previously circulating. The study’s findings have been published in eLife.

Researchers at the HSE Institute of Cognitive Neuroscience have discovered that analysing the electrical activity in the brains of a small group of people and studying their visual attention makes it possible to predict the impact of an online advertising campaign on a much larger group of 300,000 consumers. The paper has been published in Brain Sciences.

Researchers from Russia and the U.S. have found language impairment in children with Autism Spectrum Disorder (ASD) to be associated with a lower volume of grey matter and greater gyrification in the temporal and frontal lobes of the cerebral cortex. These regions play a critical role in language functioning. Understanding the structural characteristics that underlie behavioural deficits can aid in designing special education programmes for children with autism. A paper with the study’s findings has been published in Scientific Reports.
